Fuel economy by year

How it compares

Against the average standard sport utility vehicle 2wd in this dataset (about 19 MPG), the QX80 sits roughly 4 MPG below that mark on average, making it a thirstier-than-average choice for its class.

Five-year fuel cost

Fuelling a QX80 for five years at the EPA's 15,000-mile basis costs roughly $25,000 to $26,500, averaging about $25,750 across the versions here. That is the energy bill alone — it excludes insurance, maintenance and depreciation, which for most owners together exceed what goes into the tank.

How it changed over time

Between 2016 and 2020 the QX80's average combined economy slipped from about 16 to 16 MPG. Redesigns, new engines and added hybrid or electric versions are usually what move the number, so the year you choose can matter as much as the model.

Best year for fuel economy

The 2016 QX80 has the strongest average combined economy in this database at about 16 MPG, while the 2017 is the lowest at about 16 MPG. If running cost is your priority, that is the year to target on the used market; later years may add equipment or safety features instead.
